We thank Durham University for a Doctoral Fellowship (to ANS) that has facilitated our own work on anion-binding podands. 

In the same way as the molecular or supra molecular juxtaposition of a binding site and a chromophore can result in luminescent or colorimetric sensing of target substrates, so incorporation of a redox-active centre may allow electrochemical detection of binding. In Section 4.7.2, we examined a range of hosts for anions based on the Co(III)/Co(II) redox couple in cobaltocinium based podands, corands...
